Are “All IP networks” easy to automate?
• Computer networking & telecom industry has been steadily
moving towards an “all IP” world.
– Is “all-IP convergence” a simple, scalable, robust, manageable,
performing and future-proof solution for all types of computer
networks?
• Could be if
– The “IP protocol suite” had been designed with generality in mind,
allowing its protocols to adapt to specific network environments
– The “IP protocol suite” is well know for having no scalability,
performance or security issues

There is a better approach: RINA
• Network architecture resulting from a fundamental theory of computer
networking
• Networking is InterProcess Communication (IPC) and only IPC. Unifies
networking and distributed computing: the network is a distributed
application that provides IPC
• There is a single type of layer with programmable functions, that repeats
as many times as needed by the network designers
• All layers provide the same service: instances or communication (flows) to
two or more application instances, with certain characteristics (delay, loss,
in-order-delivery, etc)
• There are only 3 types of systems: hosts, interior and border routers. No
middleboxes (firewalls, NATs, etc) are needed
• Deploy it over, under and next to current networking technologies

“IP protocol suite” macro-structure
• Functional layers organized for modularity, each layer provides
a different service to each other
– As the RM is applied to the real world, it proofs to be incomplete.
As a consequence, new layers are patched into the reference
model as needed (layers 2.5, VLANs, VPNs, virtual network
overlays, tunnels, MAC-in-MAC, etc.)

Network management
Commonality is the key to effective network management

• Commonality and consistency in RINA greatly simplifies management
models, opening the door to increased automation in multi-layer
networks
– Reduce opex, network downtime, speed-up network service delivery, reduce
components that need to be standardised
From managing a set of layers, each with its
own protocols, concepts and definitions …
… to managing a common, repeating structure
of two protocols and different policies
